Abstract
The capacities of six activated carbons for the soluble organics in filtered secondary effluent were obtained by use of a continuous-flow, column-type test. Results varied from 7 to 13 grams COD per 100 grams of carbon. Because of the manner in which the test was carried out, only the carbon with the smallest capacity was loaded to the maximum extent possible. The chemical regeneration of exhausted carbon was investigated by use of nine inorganic oxidizing agents. Only hydrogen peroxide was capable of restoring measurable adsorption capacity after more than two cycles of exhaustion and regeneration. The economic feasibility of chemical regeneration is not promising. (Author)
